Abstract:We calculate the complete next-to-leading order (NLO) QCD corrections to J/ψ+W associated production within the factorization formalism of nonrelativistic QCD at the 7 TeV Large Hadron Collider. We provide the numerical results for the leading-order (LO), NLO QCD corrected differential cross sections of the J/ψ transverse momentum by adopting the event selection criteria requested by the ATLAS experiment. It is found that the differential cross section at the LO is significantly enhanced by the NLO QCD corrections.
